The transmission can be shuttle shifted without stopping the machine. The transmission is designed to downshift automatically if a direction change is selected at speeds above 12.9 km/h (8 mph). At speeds between 6.4 km/h (4 mph) and 12.9 km/h (8 mph), some clutches act as brakes in order to gradually slow the machine to 0.81 km/h (0.5 mph). Next, the directional shift is slowly made.
Forward/Reverse Shuttle

In order to change from forward to reverse travel, simply depress neutral lock button (2) and move control lever (1) fully in the rearward direction. Shifting from forward to reverse can be done at any engine speed. Also, any speed may be selected. When you shift to reverse from the "F3" speed through the "F10" speed, the electronic controls will modulate the transmission clutches in order to slow the machine to a stop. Next, the electronic controls will immediately modulate an engagement of the corresponding reverse speed. When you shift to reverse from the "F11" through "F16" speeds, the transmission will automatically downshift to "F10". Next, the electronic controls will immediately modulate the engagement of "R10".
Note: When you shift from speeds "F1" and "F2", the "R3" speed will be selected because "R3" is the lowest reverse speed. "R3" is a higher speed than "F1" or "F2". The machine will move faster in the reverse direction since "R3" is a higher speed.
Note: The reverse speed that is selected can be programmed differently than the selection that is described above. The reverse speed is programmed at 0 in the example above. The forward speed that is selected cannot be programmed.
Reverse/Forward Shuttle
When moving in speeds "R3" through "R10", depress neutral lock button (2) and move control lever (1) fully in the forward direction. The electronic controls will modulate the transmission clutches in order to slow the machine to a stop. Next, the electronic controls will immediately modulate the engagement of the corresponding forward speed. When you shift from the "R11" speed, the transmission will downshift to "R10". Next, the electronic controls will modulate the engagement of "F10". The following illustration indicates the corresponding speeds for shuttle shifting between forward and reverse.

Programming Reverse Speed Selection
When you shift from forward to reverse, the transmission will normally select the same speed in reverse that was selected for forward travel. The exceptions are described previously. When you program the transmission, the transmission will select a maximum of three speeds that are higher than the current forward speed. Also, the transmission will select a maximum of three speeds that are lower than the current forward speed. The transmission can also be programmed in order to always select the lowest reverse speed "R3".
In order to program an alternative reverse speed, perform the following steps:
- Turn the engine start switch to the OFF position.
- Move transmission control lever (1) to the REVERSE position while you hold the lever to the right.
- While you continue to hold the lever to the right, turn the engine start switch to the ON position. Do not start the engine. After 5 seconds, release the lever. Do not push the transmission control lever forward to the NEUTRAL position. The central display should show "0" unless you have programmed the transmission in order to select a higher reverse speed or lower reverse speed.
- In order to program a higher speed, push the transmission control lever to the right one time. This selects a reverse speed that is one speed above the current, forward speed. Push the transmission control lever to the right two times. This selects a reverse speed that is two speeds above the current, forward speed. Push the transmission control lever to the right three times. This selects a reverse speed that is three speeds above the current, forward speed. The display will indicate a "1", a "2", or a "3".
- In order to program a lower speed, pull the transmission control lever to the left one time. This selects a reverse speed that is one speed below the current, forward speed. Pull the transmission control lever to the left two times. This selects a reverse speed that is two speeds below the current, forward speed. Pull the transmission control lever to the left three times. This selects a reverse speed that is three speeds below the current, forward speed. The display indicates a "-1", a "-2", or a "-3".

- In order to program the lowest speed "R3", pull the lever to the left four times. An "L" will be displayed. The "L" indicates that the lowest reverse speed will be selected regardless of the preceding forward speed.
- In order to return to normal shuttle shifting, move the lever to the left or move the lever to the right in order to obtain a "0" in the central display.
- Turn the engine start switch to the OFF position in order to exit the software and save the new setting. Before you restart the engine wait for a period of ten seconds.
The electronic controls of the transmission allow various aspects of the transmission to be programmed. The transmission can be calibrated in order to maintain a quality of shifting. The electronic controls continuously monitor the performance of the transmission. Fault codes will be logged if a malfunction occurs in the transmission.
